Abstract

This study illustrates the low-cost, eco-friendly synthesis of silica nanoparticles using local bamboo leaves collected in August 2024 from the Aqqan Valley in the Al-Masimir District of Lahij Governorate, Yemen. Nanosilica powder synthesis by precipitation method is generated subsequent to thermal treatment of BLA at 750°C followed by characterization using advanced characterization techniques. The absorption peaks close to λmax = 240 nm in the UV spectrum showed silica nanoparticles, which were observed using UV-Vis spectroscopy. The presence of a siloxane group (Si-O-Si) in the experimental FT-IR spectral data indicated the high purity of the nanosilica particles. The prepared silica showed a high purity of 97.82% using XRF. The particle size determined by transmission electron microscopy (TEM) was found to be between 10.79 nm and 22.73 nm with minor agglomerations. Analysis of the nanosilica by X-ray diffraction (XRD) confirmed an amorphous structure with a
peak intensity at 2θ=23°.
